After also having taken a look at the implementation and then the
updated “Precedence” section, I'd like to argue in favor of moving `|>`
to have a higher precedence than the comparison operators (i.e. between
string concatenation and `<`). This would mean that `|>` has higher
precedence than `??`, but looking at the following examples, that
appears to be the more useful default anyways.
I'm rather interested in handling a `null` pipe result:
$user = $request->get('id')
|> $database->fetchUser(...)
?? new GuestUser();
Than handling a null callback (using the RFC example, because I can't
even think of a real-world use-case):
$res1 = 5
|> $null_func ?? defaultFunc(...);
To give some more examples of what would be possible without parentheses
then:
$containsNotOnlyZero = $someString
|> fn ($str) => str_replace('0', '', $str)
|> strlen(...)
> 0;
Which is not particularly pretty, but appears to be more useful than
either passing a boolean into a single-argument function or piping into
a boolean (which would error).
